[split] 0.999... equals 1

[Tiberius]

Ok I can dismiss fractions. I can't get the convergence thing still tho'. You may as well call it 1 because there's nothing to add to it to make it 1. But why not just call it '1'?

You may as well, but the point is it is an example of how (going against all common sense) a number can be represented more than one way in the decimal system. As the article says, a lot of students simply refuse to accept the fact because they've always assumed that no two decimal numbers can equal one another.

You could also claim that 2 - 0.9r = 1

Hmm ..I guess I get it

Yay! Indeed, 2 - 0.9r = 1.
Also, 2 - 0.9r = 0.9r given that they are the same thing

Thanks for taking the time to explain it.

No problem. May you go out into the world with a brand new perspective on infinity
